Multiple melting endotherms in melt-crystallized nylon 10,12
Li, YJ; Zhu, XY; Tian, GH; Yan, DY; Zhou, EL
AbstractThe melting behaviour of melt-crystallized nylon 10,12 was investigated by differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD). The results show that all nylon 10,12 crystals obtained under various conditions, including isothermal, non-isothermal and stepwise crystallization, and also after partial melting or annealing, show multiple melting behaviour. It was found that each melting endotherm has a different origin. The highest melting peak corresponds to melting of the recrystallized material while the other melting endotherms are related to melting of lamellae with different thicknesses developing under different crystallization conditions. The equilibrium melting point of nylon 10,12 was also firstly estimated to be about 206 degreesC. (C) 2001 Society of Chemical Industry
